DESCRIPTION

Personal hygiene composition for a keratin substrate comprising cationic conditioning and / or styling tetrapolymer

Field of the invention

The present application relates to a personal hygiene composition and, more particularly, to a personal hygiene composition comprising a conditioning and / or styling copolymer for a keratin substrate of hair and / or skin origin.

Background of the invention

Undamaged virgin hair is soft and shiny; its cuticles on the surface of the hair gently rest, facilitating styling. The surface of the hair is also hydrophobic in nature which prevents excessive water absorption during washing. When hair is mechanically damaged by teasing, heavy brushing, or chemically damaged by bleaching, perming, or coloring, the hair surface becomes rough and frizzy and difficult to detangle and style. As the surface of the hair becomes more hydrophilic, the resulting hair fibers swell during washing, making the hair more difficult to style.

Current conditioning and / or styling systems for regular or damaged hair generally use one or more combinations of cationic surfactants, amphoteric surfactants, silicones, fatty alcohols, polyquaterniums, amino acids, proteins, lipids, and humectants. Wet conditioning of regular or damaged hair is accomplished by neutralizing the hair's anionic charge by positively charged surfactants and polymers and creating a hydrophobic layer from the surfactant and polymers. This hydrophobic layer results in a reduction in the swelling of the hair fibers making the hair more hydrophobic and thus smoothing the cuticle layers and reducing the friction of the hair fibers. An overall result of wet conditioning is better detangling, manageability, and a soft feel to the hair. With treatment with cleansing systems such as shampoos, 2/1 shampoos, body soaps or shower gels, styling behavior, detangling properties, hair hydrophobicity and lubricity are not sufficiently maintained.

Example 1: Application of wet combability conditioner - Long-lasting effect of DADMAC tetrapolymer [DADMAC / AA / BEM / VCAP (95.3 / 2.5 / 2 / 0.2)]

Texture Analyzer Styling Measurements: The styling measurement of hair strands treated with a conditioning composition comprising DADMAC tetrapolymer (Table 1) was performed on a texture analyzer without manual hair detangling. The energy required to comb the lock was indicated in the list as gf-mm. For each measurement, 3 bleached hair strands were used and the average was calculated. To measure the long-lasting conditioning of the lock, it was first treated with 0.2 g / g of hair conditioner, which was then rinsed and the styling energy was measured. After the measurement, the hair was washed with the non-conditioning shampoo once, the styling energy was measured 3 to 5 times. No conditioner was applied between them. The results are shown in FIG. 1.

Compared to a commercial silicone-containing conditioner, DADMAC tetrapolymer conditioner exhibited excellent long-wear performance with silicone and without silicone (at this point ease of wet combing) after rinsing was shampooed 1/3/5 times non-conditioning (2% CAPB and 12% SLES shampoo base).

Example 2: Determination of hydrophobicity by measuring the contact angle:

The contact angle is the indication of the superficial hydrophobicity of the hair. The intermediate and long-term hydrophobicity of tetrapolymers were studied by measuring the contact angle after several washes with a shampoo containing tetrapolymer. The method was as follows: (i) a portion of the hair strand was stretched on a specially designed plate so that the fibers were suspended together in space to form a "single" surface (ii) A drop of deionized water was supplied from a syringe on the fiber surface. The droplet mass is ~ 0.008 g, (iii) images were collected at 1 s or 10 s intervals.

The greater the contact angle, the more hydrophobic the surface is. Undamaged virgin brown hair is hydrophobic by nature, but all chemical treatments, such as bleaching, reduce the hydrophobicity of the hair. Virgin hair contact angle is approximately 110, which is reduced to 85 with bleaching. Likewise, the drop of water applied to the surface of the hair is absorbed in 60 s. On virgin hair, the drop can remain for several hours. The results demonstrate (FIG. 2 and FIG. 3) the influence of (0.2% by weight) of tetrapolymers supplied from a shampoo on the contact angle. It is concluded that repeated treatment with tetrapolymer-containing shampoos leads to a restoration of the hydrophobicity of damaged hair close to the level of virgin hair. The results of the hydrophobicity test are provided in Table 1, Figure 2 and Figure 3.

Compared to full-formula commercial shampoos with polymers, conditioners and silicones and without silicones, the shampoo containing DADMAC tetrapolymer has the best long-lasting benefits, being superior after three hair washes compared to commercial shampoos.

Example 3: Composition of wet styling ease shampoo:

Styling measurement of hair strands treated with shampoo containing tetrapolymer was performed on an Instron device. The energy required to comb the lock was reported as gf-mm. For each measurement, 3 strands of bleached hair were used and the average was calculated. To measure long-lasting conditioning, the lock was first treated with 0.1 g / g hair shampoo, which was then rinsed and styling energy was measured. The lock was washed 2 more times and the styling energy was measured again. Wet styling energy results after 1 and 3 washes are reported in FIG. 4 and Table 2 for DADMAC homopolymer (PQ6) and DADMAC tetrapolymer shampoo compositions.

From the results of the wet combability for the tetrapolymer shampoo compositions, it can be deduced that the conditioning performance of the tetrapolymer shampoo is even better compared to PQ6. The shampoos were applied to damaged hair, 0.1 grams per gram of bleached hair (bleached 1 hour) and the wet combing energies were measured after 1 and 3 and 5 times of washing with 0.1 grams per gram of experimental hair shampoo. Both homopolymer-containing and homopolymer-containing shampoos outperformed commercial silicone-free shampoo.

Example 4: Sensory evaluation

A trained panel of experts evaluated the sensory properties of the treated hair strands and the results were highly correlated with the measured values, eg styling energy values. Sensory properties are an essential part of consumer acceptance. With the help of sensory evaluation, long-term properties can be determined after multiple uses.

WET STATE

continuation

Tetrapolymers at 0.2 % by weight of active were used together with 12 % by weight of SLE2S, 2 % by weight of CAPB by adding 100% water. Next, the simple shampoo formula was applied to the hair at 0.3 g / g of bleached Caucasian hair and washed and rinsed. After drying at room temperature, it was evaluated. The procedure was then repeated 2 more times and the samples were evaluated. The following test shampoos and market reference shampoos with tetrapolymers of the present application were compared for sensory evaluation ( Table 3).

In the wet state, after a washing evaluation of the wet behavior of the hair strands, it exhibited detangling properties and the rest of the properties were normal. However, after three washes of the hair strands, there was a great difference in each of the parameters of the evaluation carried out ( Table 4) considered, except for stickiness. The results demonstrated the advantages of the composition comprising DADMA ^c tetrapolymer of the present application. The results are provided in ( Figures 5 and 6.

In cases of evaluation of the dry state, the compositions comprising DADMAC tetrapolymer showed a better performance for most of the evaluation parameters after washing the hair strands, and where hydrophobicity, detangling and ease of combing showed better behavior that are directly related to the styling and manageability of the hair strands. Whereas, after 3 washes of the hair strands, these benefits were further improved. The results of the evaluation in the dry state are given in Table 5 and Figures 7 and 8 .
